"Unearthed: Ancient Fish with Record-Breaking Underbite"

Scientists have discovered that the ancient fish Alienacanthus had one of the most extreme underbites ever recorded, with an immensely elongated lower jaw studded with teeth. This placoderm fish from the Devonian period had a unique jaw mechanism that allowed its upper jaws to move independently of the skull to accommodate its lengthy lower jaw. Researchers believe that Alienacanthus may have used its underbite to trap live prey, and its discovery sheds light on the diverse jaw forms and proportions that evolved during the Late Devonian period.
